 specimens at Highlands, shows that for the production of seeds 

 crossfertilisation l)y insects is necessary.

 without exception fertilised l)y large carpenter-bees {Xylv'-opa

 are dispersed. 



Two papers were read to the Linnean Society, Init. it seems, 

 were not printed : ''On the Stone-Grasshopper of Grahainstoivn, 

 South Africa'" (Proc. Linn. Soc, Feb. 4th, LSGO) and "-On 

 Carnivorovs and Insectivorous Plants"' (Proc. Linn. Soc, Dec 

 1st., 187())- Tl^^ observations in the former have, however, been 

 referred to by Trimen and others. 



Her best known paper is perhaps the following : 



^'- Notes on the peculiar habits and changes which take place 

 in the larva of Papilio Nireus.''" Trans. Knt. Soc, 1874, p. 

 519-521 (with Plate IX). 



Mrs. Barber was one of the first to discover the variable i)ro- 

 tective resenil)lance in the pupae of certain butterflies, and to 

 discuss its ])robable causes. Papilio Nireos will, thanks to Mrs. 

 Barl)er"s paper, remain a classic example of this peculiar power of 

 adaptation (See K. B Poulton 'The colours of animals," Inter- 

 national Science Series, Vol. LXVIII, LSiH). p. 115-118, 129). 



In her correspondenr-e with friends, some of whom have been 

 mentioned before and which included some of the foremost men 

 of her time, she must have simply been bul)bling over with in- 

 teresting facts discovered by her. Many of the works of these 

 friends have numerous citations from her letters, e.g. Layard and 

 Sharpens ''Birds of Sovith Africa," Trimen's ''South African 

 Butterflies," Harvey's "Thesaurus Oapensis." Many of her plants 

 were mentioned in the "Flora Capensis" and other botanical 

 publications and many of her discoveries of new species of insects 

 and plants were named after her. The genus Barberetta was 

 named by Harvey in her honour, and the genus Bowkeria was 

 deilicated to her and her brother, Col. Bowker. I will let two of 

 these friends speak for themselves to show the value of her con- 

 tributions. K. Trimen, in the preface to his " South African 

 Butterflies" (p. IX), says : 



"To Mrs. F. W. Barber, the sister of Colonel Bowker, I am
